Sensor open error (temperature sensor variant)

From Service Manual 934416, p.28:

1.Check if the sensor is disconnected; check sensor wire and housing connection to main PCB connector.

2.Disconnect the sensor and measure resistance at the sensor body. Expected: 10 kΩ to 12 kΩ at 77°F (25°C).

3.Check the sensor harness for opens and shorts. Back-probe the sensor pins at the control board connector; a reading outside 5 kΩ to 50 kΩ indicates a failed sensor.
